1 Introduction
Security is among the critical things that must be ensured in any organization. In every
organization, the security of information is simply done in the server side and this requires the
administration to ensure that its data is secure. Since a large portion of the task keeps on running
at a full-time premise, nobody can probably observe all edges of the association at a prior.
To avoid issues of framework server failures, there is a need for a few apparatuses that ensure
legitimate checking. In this examination report, we are going to think about the execution and the
utility of a portion of the server accessibility, observing devices including yet not restricted to;
Nagios Core, Ganglia, CollectD, Spiceworks, Cacti, Zabbix, Icinga, OpenNMS and WhatsUp
Gold as for the measurements we will consider in the following segment.

of the space
available.
It provides a free
source integration to
fit all the desires of
the IT users the same
way Nagios does.
Can be used best by
the administrators to
fix and monitor
latencies issues.
This is seen in both
the status and the
performance per the
network.
3 Evaluation
3.1 Ganglia
Higher performance systems used in computing works well with this type of monitoring tool
since it’s scalable and distributed [4]. Mostly bundled with the Linux operating systems. With
this said, ganglia turn to be the best in monitoring the state of the host, provides information
relating to the changes that occur, uses unicast or the multicast listening of nodes and provide
feedback to all the XML cluster description.
3.2 Spiceworks
This is best designed for an organization operating with less than 1000 devices within a given set
of network devices [5]. With Spiceworks, IT issues can be easily resolved hence allowing for
effective and efficient performance. All the information is centralized for the members to get all
alerts through their email addresses. Once set up, the new trends and overflow analysis is made
easier.

3.2 Architecture
4 Solution proposal
With the wild events of the server vulnerabilities, there should be a shield of the system
framework on top of the systems administration checking instruments. Servers should be all
around overseen [6]. As an assurance component for security, we will think about utilization;
a) Ensure data security; Very sensitive information must be kept well. This can be done through
encryption and keeping well the decryption key. When sending this information to another
person, ensure that it's properly protected.
b) Encrypting all the devices in the organization.
The organization should make computer data encryption policy to ensure that every member of
the organization practice data encryption because computers that are not encrypted, they are at
great risk of attack.

5 Failure Prediction Impact
With the expansion in systems administration tasks, Preventive measures must be put in place in
the organization [7]. This will include:
a) Takes into the record the nature of the general execution. With all the administration setups,
the quality is considered to ensure future development of the foundation.
b) One should be additionally ready to anticipate for the examination and utilizing the
investigation about the assailants.
6 Conclusion
From the above information, we can reason that to have the best execution in an association, we
need checking instruments off the top dimension for fast caution. In this report we've analyzed
the different devices that can be used for server security, even though there must be ways out for
a distinction, having somewhere around will ensure security in the entire organization.
